What Is a DSO? Why It Matters for Your Dental Care

What Does DSO Stand For?

DSO stands for Dental Service Organization. A DSO is a separate business entity that contracts with dental practices to handle their non-clinical operations. That includes things like billing, marketing, human resources, payroll, IT, and supply purchasing. The dentist still treats patients, but the business side of the practice is managed by the DSO.

According to the Association of Dental Support Organizations (ADSO), the stated purpose of a DSO is “to allow dentists to maximize their practice with the support of professional operations management.”

How Does a DSO Work?

In a typical DSO arrangement, the organization acquires a dental practice or partners with one. The DSO then takes over ownership of equipment, real estate, and employment of non-clinical staff. The dentist continues to provide patient care, but the business decisions are made by the DSO.

There are different types of DSO models:

• Full ownership DSOs buy the practice outright and employ the dentist.
• Management service organizations (MSOs) provide support services while the dentist retains some ownership.
• Invisible DSOs acquire practices but keep the original doctor’s branding, so patients may not know the practice has changed ownership. The term “invisible DSO” refers to a DSO that owns all or part of multiple practices through acquisitions while retaining each doctor’s original branding, according to industry definitions.

How Big Are DSOs in the U.S.?

DSO-affiliated dentistry has grown rapidly over the past two decades. According to ADA Health Policy Institute research (2024), 27 percent of dentists less than 10 years out of dental school are now affiliated with a DSO, up from 24 percent in 2023. Among dentists who graduated more than 25 years ago, only 9 percent are DSO-affiliated.

The broader trend is clear: practice ownership among U.S. dentists dropped from 84.7 percent in 2005 to 73 percent by 2021, according to the ADA’s practice ownership data. Among dentists under 35, the share who own their practice has nearly halved in the past decade.

Why DSOs Are Growing

Several factors drive DSO growth:

• Dental school debt. New dentists graduate with significant student loan debt, making the upfront cost of buying or starting a practice harder to manage.
• Administrative complexity. Running a dental practice means managing insurance claims, HR, compliance, and technology. DSOs handle all of that.
• Work-life balance. Many younger dentists prefer to focus on clinical work without the stress of business ownership.
• Economies of scale. DSOs negotiate better rates on supplies, equipment, and insurance contracts by operating across many locations.

What This Means for You as a Patient

The growth of DSOs affects your dental care in several ways:

You may already be visiting a DSO-affiliated practice without knowing it. Many DSOs keep the original practice name and branding after acquisition. The dentist you have been seeing for years may now work under a DSO, and the office might look exactly the same.

Treatment decisions may be influenced differently. In a DSO model, there can be production targets or treatment quotas that come from the corporate level. In an independently owned practice, the dentist who treats you is typically the same person making all clinical and business decisions.

Continuity of care can vary. DSO practices sometimes experience higher dentist turnover. ADA research on practice transitions among new dentists found that dentists who left affiliated (DSO-type) practice settings reported significantly higher increases in satisfaction for schedule flexibility (53 percent increase) and clinical autonomy (62 percent increase) compared to those who left unaffiliated settings.

Pricing and insurance networks can differ. DSOs often accept a wide range of insurance plans due to their negotiating power. Independent practices may accept fewer plans but could offer more flexibility on pricing and payment arrangements.

How to Tell If Your Dentist Is Part of a DSO

It is not always obvious. Here are a few ways to find out:

• Ask directly. Your dental office should be willing to tell you about their ownership structure.
• Check the practice website for corporate affiliations, parent company names, or “part of the [X] family” language.
• Look up the practice on your state dental board website.
• Search the practice name along with “DSO” or “dental service organization” online.

The Bottom Line

A DSO is a business model, not a measure of quality. There are excellent dentists working in DSO-affiliated practices, and there are excellent dentists running their own independent offices. What matters most is the quality of care you receive, the transparency of treatment recommendations, and whether you feel comfortable with your provider.

Understanding what a DSO is gives you the information to ask better questions and make informed choices about your dental care. If ownership structure matters to you, ask your dentist about it. You have every right to know.
